We're dividing 30063174 by 866 
Our goal is to divide 30063174 by 866.

Let's proceed to step 1:
The number 866 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 866

Advancing to step 2:
30 divided by 866 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 866

Advancing to step 3:
The number 866 fits into 300 0 times, leaving a remainder of 300.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 300 leaves us with 300.
Append the next digit (6) from the dividend to 300 and continue with: 3006 / 866

Advancing to step 4:
866 can be fit into 3006 3 times, resulting in a remainder of 408.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 2598 away from 3006, we end up with 408.
Fetch the next digit (3) from the dividend, attach it to 408 and continue: 4083 / 866

Step 5:
866 goes into 4083 4 times with a remainder of 619.
Put 4 as the next digit of the answer. 
Result so far: 34.0
The remainder is 619 after subtracting 3464 from 4083.
Fetch the next digit (1) from the dividend, attach it to 619 and continue: 6191 / 866

Going ahead to step 6:
866 goes into 6191 7 times with a remainder of 129.
The next digit of our result is 7. 
Result so far: 347.0
Subtract 6062 from 6191 to get 129.
Take the next digit (7) from the dividend and append it to 129, then repeat: 1297 / 866

Step 7:
866 can be fit into 1297 1 times, resulting in a remainder of 431.
Put 1 as the next digit of the answer. 
Result so far: 3471.0
Deduct 866 from 1297 and we're left with 431.
Grab the next digit (4) from the dividend, add it to 431, then carry on: 4314 / 866

Let's proceed to step 8:
866 goes into 4314 4 times with a remainder of 850.
Write down 4 as next digit of the result. 
Result so far: 34714.0
Subtract 3464 from 4314 to get 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8500, and continue the process.

Advancing to step 9:
866 can be fit into 8500 9 times, resulting in a remainder of 706.
Record the quotient 9 as the next digit in the result. 
Result so far: 34714.9
Subtracting 7794 from 8500 leaves us with 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Let's proceed to step 10:
866 can be fit into 7060 8 times, resulting in a remainder of 132.
Put 8 as the next digit of the answer. 
Result so far: 34714.98
Deduct 6928 from 7060 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 11:
If we divide 1320 by 866, we get 1 and a remainder of 454.
The number 1 becomes the next digit in our result. 
Result so far: 34714.981
Subtracting 866 from 1320 leaves us with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Going ahead to step 12:
If we divide 4540 by 866, we get 5 and a remainder of 210.
Put 5 as the next digit of the answer. 
Result so far: 34714.9815
Subtract 4330 from 4540 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 13:
When dividing 2100 by 866, we get 2 with a remainder of 368.
Record the quotient 2 as the next digit in the result. 
Result so far: 34714.98152
Deduct 1732 from 2100 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 14:
When dividing 3680 by 866, we get 4 with a remainder of 216.
The next digit of our result is 4. 
Result so far: 34714.981524
Subtracting 3464 from 3680 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 15:
866 can be fit into 2160 2 times, resulting in a remainder of 428.
Record the quotient 2 as the next digit in the result. 
Result so far: 34714.9815242
If we subtract 1732 from 2160, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 16:
866 goes into 4280 4 times with a remainder of 816.
Put 4 as the next digit of the answer. 
Result so far: 34714.98152424
Subtracting 3464 from 4280 leaves us with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

The final outcome is 34714.98152424, with a leftover of 8.16e-07.
